Hey there @TurboCharge, welcome to the site!

To answer your questions:

1. When you export items from the adventure, unfortunately most can't be brought back. Only a few types of items can be imported to the adventure, like technique scrolls, adventure potions, pixcoins (PC), and pixpet tickets (PPT). For the pumpkin and blue bed, sadly you'll have to restart the adventure with a different pet in order to get those again. I'm really sorry about that. :(

2. When your pet reaches fully glitched in the adventure, they'll be temporarily unable to continue until you heal them with an Adventure De-Glitch Potion. You can find these either at potion shops (such as Slith's Potion Shop at the Entrance Gate) or by brewing them yourself at the cooking stations. Personally I find it easier to buy them from shops.

3. I've made a list of scrolls that Canisqua can learn (that I know of) and their locations, take a look under the spoiler:


4. I think I saw that Cherche was helping you with naming your pet? But if you need any further help with this, please let us know :)

I hope that helps somewhat, but please don't be afraid to ask more questions if you have any!
